Some really good tips:
- as soon as you know the language good enough to understand the basics, change the operational language in as many electrolical devices you can.
- use the language every day. If you spend only half an hour a day (those days that you don't practice it normally, like when you dont have language lessins, etc.) to just use it as much as you can, your brain will use more space on it, and you'll learn the language quicker
